How to file an income tax return in Pakistan on IRIS

Most filing problems in Pakistan are not portal problems. They are sequence problems: people open IRIS first and try to assemble the numbers inside the form. The screens then dictate the order of work, gaps get plugged with estimates, and the wealth statement will not reconcile. This guide runs the sequence that actually works — reconcile, compute, then file.

Deadlines, before anything else

Extensions are granted by notification in some years and not others, and an individual extension under section 119 requires an application to and approval from the Commissioner. Plan to the statutory date and treat any extension as a bonus. Confirm the current position on the FBR due dates page rather than on a news headline.

Step 1: build the reconciliation pack offline

Before opening IRIS, assemble four groups of evidence. If any group is incomplete, filing is premature.

• Income evidence. Salary certificate and tax deduction certificate for the full year and from every employer; business accounts; rent agreements and receipts; dividend and profit-on-debt certificates; capital gains statements from your broker or CDC; foreign income records.
• Tax already paid. Withholding certificates, advance tax challans, and — critically — the FBR record of tax deducted against your registration. Claim only what is both certificated and visible in FBR's records; a mismatch here is one of the fastest routes to a notice.
• Assets and liabilities. Property, vehicles, bank balances, investments, business capital, receivables, foreign assets, and every loan or credit facility, valued at year end.
• Cash movement. Full-year bank statements for every account, plus records of gifts, inheritances, remittances and capital introduced or withdrawn.

The document checklist sets this out in a form you can work through line by line.

Step 2: build the wealth bridge before you compute tax

This is the step that separates a return that survives scrutiny from one that does not. The wealth statement has to explain how you got from opening net worth to closing net worth. The bridge is simple to state and unforgiving in practice:

Worked in outline: opening net assets of Rs 12,000,000, declared income of Rs 3,600,000, a documented gift received of Rs 500,000, personal and household expenses of Rs 1,800,000, and a vehicle purchased for Rs 2,500,000 should produce closing net assets of Rs 11,800,000 once the vehicle is added back as an asset rather than treated as an expense. If your closing figure differs, find the transaction — do not adjust the expense line until it fits.

Two patterns reliably attract attention: an unexplained increase in assets, and household expenses declared at a level inconsistent with the declared lifestyle, family size and location. FBR's analytics are explicitly built to flag the second. The reconciliation guide works through how to trace a difference rather than plug it.

Step 3: the IRIS sequence

1. Log in and check the taxpayer profile. Confirm the registered email, mobile, address and business activity are current and under your own control. An outdated profile misdirects notices — see updating the IRIS profile.
2. Select the correct tax year and return form. Salaried, business individual, AOP and company forms differ. Filing on the wrong form is a revision waiting to happen.
3. Enter income by statutory head. Salary, business, property, capital gains, other sources and foreign income are separate heads with separate rules. Do not merge them.
4. Enter deductible allowances and tax credits that you can evidence.
5. Enter tax already paid. Withholding by section and advance tax challans, matched to certificates and to FBR's own record.
6. Complete the wealth statement from the bridge you already built. Do not build it here for the first time.
7. Review the computed liability or refund against your offline computation. If the two differ, stop and find out why before proceeding.
8. Pay any balance by generating a PSID, checking taxpayer, tax year, payment head and amount, then paying through your bank or the payment channel you use. Confirm the credit appears against the correct year. See paying tax through a PSID.
9. Submit — not save — and download the acknowledgement.

The gap between step 8 and step 9 catches people out every year. A PSID generated is not a payment made, and a return saved is not a return submitted.

Step 4: after submission

• Download and store the submitted return, wealth statement, computation and acknowledgement together, named by tax year.
• Verify that the payment has attached to the correct tax year and head.
• Watch for Active Taxpayer List inclusion on the next refresh cycle — the list is published on 1 March following the tax year and updated weekly. See how ATL status works.
• Store the supporting evidence pack with the return, not in a separate folder that will be hard to reassemble in two years.

What late filing costs from 1 July 2026

The economics changed with the Finance Act 2026. A late individual filer now faces a section 182A restoration surcharge of Rs 25,000 rather than Rs 1,000, an association of persons Rs 50,000, and a company Rs 100,000. A section 182 penalty computed on tax payable and days of default may apply on top, subject to statutory minimums and caps. And throughout the period off the Active Taxpayer List, every documented transaction is withheld at the higher rate.

An individual may alternatively furnish an undertaking to the Commissioner not to acquire immovable property for six months. That is a genuine option for some taxpayers and a trap for anyone with a property transaction in the pipeline. Late filing consequences covers the sequence in more detail.

Six mistakes that turn a filing into a notice

1. Filing before bank statements are reconciled. The wealth statement will not hold together and the difference gets plugged.
2. Claiming withholding that is not in FBR's records. Certificates alone are not enough if the deduction was never deposited against your registration.
3. Omitting an asset because it produced no income. A dormant plot, an idle account or a vehicle in someone else's custody still belongs in the wealth statement.
4. Declaring implausible household expenses. Analytics flag the mismatch between declared expenses and declared lifestyle faster than any human reviewer would.
5. Letting a consultant own your IRIS credentials. You lose the ability to check what was filed in your name.
6. Treating submission as the end. Payment credit, acknowledgement retention and ATL confirmation are all part of the job.

If you are filing for the first time, start with the first-time filer guide, which deals with opening assets and prior-year funding sources. If a notice has already arrived, send us the notice reference and the tax year before replying to it.
